The example demonstrates different axis scale types for the surface charts.<br><br>
Like an <a href="XYChart.htm">XYChart</a>, in a <a href="SurfaceChart.htm">SurfaceChart</a>, the axis scale can represent numbers, date/time or labels. In this example, the x-axis uses a date/time scale, the y-axis uses a label based scale, and the z-axis uses a numeric scale.
